Paul, and everyone,

1.  Thanks to everyone who has replied.  I appreciate your knowledge and 
willingness to help.  In particular, 3 different individuals from Kawai 
USA technical service have advised that I can buy original scale 
replacements from Mapes.

2.  The hammers are what they are.  When was the last time you sold the 
buyer of a $500 used electric piano a shaping, regulation, and voicing job?

3.  "Major defect"?  No such assumption has been made.  My question, for 
those experienced in designing bass scales, is whether, based on this 
piano's history plus any additional experience you might have with this 
model, you would advise designing the missing strings at a % break 
strength of 60% like the neighboring strings, or perhaps going a little 
lower.

thanks

Mike Spalding
